One of our Cuckoo EEs recently acted like she was egg bound and so we attempted to take action and help her, but unlike we thought, there was no egg inside her that we could feel. Her vent looks wrong. One of the "lips" on her vent is purplish and looks slightly bruised or swollen, we suspect that she may have had trouble passing an egg recently and injured it somehow. About a week ago we found an egg in the run with a lot of white membrane attached to the shell. I now suspect that was her last egg and she injured her vent in passing it and we have not had any of her eggs since. Has anyone had something like this happen before and or does this sound familiar and how can we help her? We did egg bound treatments to her last night such as giving her calcium and putting her in warm bath and lubricating her vent. She is still acting funny and we are not sure what the next step should be, we have her separated from the other hens and in a isolated place inside the house currently. Could it be just her vent and if so what would we put or give her to help? (I took picture of her vent but I have it on other device and can add later if needed).
